Was reading about the WannaCrypt attacks. If you have the MS17-010 bulletin patches installed in your estate, you are safe. I wanted to quickly scan our estate to see if the servers are patches with this. Not my job really, but I wanted to do it anyways.

The security bulletin page lists the actual patch numbers for each version of Windows. We only have Server 2008 – 2016 so that’s all I was interested in.

Here’s a list of the Server name, internal version, and the patch they should have.

Server 2008 | 6.0.6002 | KB4012598

Server 2008 R2 | 6.1.7600 | KB4012215 or KB4012212

Server 2012 | 6.2.9200 | KB4012214 or KB4012217

Server 2012 R2 | 6.3.9600 | KB4012213 or KB4012216

Server 2016 | 10.0.14393 | KB4013429

One thing to bear in mind is that it’s possible a server doesn’t have the exact patch installed, but is still not at any risk. That is because since October 2016 Windows patches are cumulative. So if you don’t have the particular March 2017 patch installed, but do have the April 2017 one, you are good to go. The numbers above are from March 2017 – so you will have to update them with patch numbers of subsequent months too to be thorough.

Another thing – I had one server in my entire estate where the patch above was actually installed but turned up as a false positive in my script. Not sure why. I know it isn’t a script issue. For some reason that patch wasn’t being returned as part of the “Win32_QuickFixEngineering” output. Am assuming it wasn’t installed that way on this particular server.
